Protective textile with tungsten and manufacturing method thereof

Abstract

In one aspect, a method of manufacturing a protective textile may include steps of (a) twisting a first yarn with a tungsten filament; and (b) using a second yarn to cover the yarn-tungsten product generated in step (a). The yarn generated in step (b) is further twisted with an elastic spandex. In one embodiment, the first yarn is selected from a group of Nylon, Polyethylene Terephthalate (PET), cotton yarn, bamboo fiber and Tencel. In another embodiment, a Polyethylene (PE) fiber is the second yarn, and the third yarn may include Nylon, PET or PE. The protective textile is advantageous because it is light, thin, soft and highly cut resistant. Also, it has great electrical conductivity and chemical stability, and it is not easy to deform after washing.

What is claimed is: 
     
       1. A method of manufacturing a protective textile comprising steps of:
 (a) twisting a first yarn with a tungsten filament; and 
 (b) covering the first yarn-tungsten generated in step (a) with a second yarn, and 
 (c) twisting an elastic spandex with a yarn generated in step (b), and the tungsten is 60 to 80% and spandex is 20 to 40%, 
 wherein a degree of twist is 400 to 700 twists/meter in step (a) and 120 to 280 twists/meter in step (b). 
 
     
     
       2. The method of manufacturing a protective textile of  claim 1 , wherein the tungsten filament is 35 to 75% and the first yarn is 25 to 65% in step (a). 
     
     
       3. The method of manufacturing a protective textile of  claim 1 , wherein the first yarn is selected from a group of Nylon, Polyethylene Terephthalate (PET), cotton yarn, bamboo fiber and Tencel, and a line density of the first yarn is 40 to 140D. 
     
     
       4. The method of manufacturing a protective textile of  claim 3 , wherein a line density of Nylon is selected from a group of 40D, 50D, 70D, 100D and 140D. 
     
     
       5. The method of manufacturing a protective textile of  claim 1 , wherein a diameter of the tungsten filament is selected from a group of 0.01 mm, 0.015 mm, 0.02 mm, 0.025 mm and 0.03 mm. 
     
     
       6. The method of manufacturing a protective textile of  claim 1 , wherein a Polyethylene (PE) fiber is the second yarn, and the tungsten filament is about 35 to 65% and PE fiber is about 35-65% in step (b). 
     
     
       7. The method of manufacturing a protective textile of  claim 6 , wherein a molecular weight of the PE fiber is 10 to 500W, and a line density of the protective textile is 50 to 400D. 
     
     
       8. The method of manufacturing a protective textile of  claim 6 , wherein a line density of the PE fiber is selected from a group of 50D, 100D, 150D, 200D, 300D and 400D. 
     
     
       9. The method of manufacturing a protective textile of  claim 1 , wherein the elastic spandex can be a third yarn covering a spandex, and the third yarn is selected from a group of Nylon, PET and PE. 
     
     
       10. The method of manufacturing a protective textile of  claim 9 , wherein the elastic spandex can be made by spandex with a line density of 20 to 100D and the third yarn with a line density of 50-200D, and the degree of twist is 180 to 580 twists/meter. 
     
     
       11. The method of manufacturing a protective textile of  claim 10 , wherein a tension ratio of the elastic spandex is 1.5 to 2.4.
